1 Claim. (C1..81- 16.4.):

invention relates: to improvements-in tools and has particular reference toa wrench.

The principal object of this invention is to produce a combined pipe and monkey wrench.

A further object is to produce a wrench which is economical to manufacture, one which may be quickly converted from one type of wrench to another, and a wrench which occupies a, minimum amount of space.

A further object is to produce a wrench which may be used for clamping purposes; as, for instance, in holding articles to be drilled in a drill press.

A still further object is to produce a wrench which may be manufactured from standard parts, thus eliminating complicated machining.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Fig. l is a side elevation wrench,

Fig. 2 is a cross-sectional view, taken on the line 2-2 of Fig. 1,

Fig. 3 is a cross-sectional view, taken on the line 3--3 of Fig. l, and

Fig. 4 is an enlarged detail cross-sectional view, taken on the line 4-4 of Fig. 1.

Ordinarily, it is necessary to employ one type of wrench for one type of work; as, for instance, a wrench, the jaws of which have teeth.adapted to bite into the material for rotating a round object, such as a, pipe, and it is necessary to have a wrench with flat surfaces for the turning of hexagonal or square-shaped objects. Therefore, a plumber or other mechanic, must carry two different wrenches in order to meet both conditions.

Also, it is oftentimes necessary to clamp parts together which cannot be accomplished with the ordinary wrench, due to the fact that the ordinary wrench is operated by a thumb nut so that the jaws will move toward or away from each other.

Applicant has, therefore, devised a wrench which can be used for either round objects or' flat-surfaced objects and yet a, wrench which may of my improved be very easily tightened with a grip far in excess of that ordinarily employed with the common type of wrench. By providing such a grip, the device may also be used as a. clamp; as, for instance, in holding objects together or for holding 2 objects; during a machining. operation, which could nottbeheld hand.

In the accompanying drawings, wherein, for the purpose of illustration, is shown a preferred embodiment of my invention, the numerals 5 and 6 designate a pair of parallel bars having their ends positioned in a head 1, and a bottom piece 8. which act as spreaders so as to hold the rods in parallel position. These spreaders also serve to support a rotary screw 9, which has threaded engagement with a traveller I I.

The screw9, has a nut I2, at one end thereof and a handle l3, at the opposite end thereof, which handle is keyed as at M, to the screw 9.

Within this handle I form an opening l6, through which I may position the shank A, or the arm B, of a screw driver having a hexagonal cross section, the bit of which is shown at C.

A spring press ball l1, serves to retain the screw driver in the handle when the same is not being used, as shown in full lines in Fig. l.

Removably attached to the head I, is a toothed jaw l 8, detachably held thereto by a set screw IS. A similar jaw 2|, is removably secured to the traveller I I. The free ends of these jaws are bifurcated so as to surround the rod 5, as shown in Fig. 2.

The result of this construction is that, when the parts are assembled, as shown in Fig. 1, by removing the screw driver from the full-line position and positioning it in the lower dotted-line position, the handle l3 may be rotated, causing the traveller to be moved toward the head I.

If the jaws I8 and 2| are in place, then a round object such as a pipe, may be engaged thereby and through the leverage action of the screw driver in the handle I 3, great pressure can be exerted.

When the jaws l8 and 2|, are removed, as accomplished by using the screw driver, as shown in the upper dotted lines, then the wrench becomes an ordinary smooth-faced wrench, commonly called a monkey wrench.

It will thus be seen that I have produced awrench that will accomplish all of the objects above set forth.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that various changes relative to the material, size, shape and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claim.

Having thus described my invention, I claim:

A wrench comprising a pair of parallel rods.

spaced spreaders secured to said rods for maintaining said rods in parallel position, a traveller slidably mounted on said rods, screw rotatably mounted in said spreaders and having threaded engagement with said traveller, said traveller and one of said spreaders forming cooperating jaws, the adjacent faces of said jaws being parallel plane surfaces and the outer free portions of said jaws being provided with plane surfaces parallel to the said adjacent equal length and having plane surface outer ends at right angles to said adjacent surfaces, a removable jaw on each of the first mentioned jaws, each of said removable jaws being generally U- shaped and having a long leg engaging a respective adjacent surface of a first mentioned jaws and having a short leg fitting tightly on a respective parallel surface of a first mentioned jaw, each said removable jaw having portion fitting tightly against the end of a respective first mentionedjaw, the long leg of each removable jaw being bifurcated and engaging one of said parallel rods, and set screws carried by said short legs surfaces, said jaws being of 10 and engaging the first mentioned jaws, the confronting surfaces of said long legs being concave and provided with teeth.
